#1. The Currency Challenge: Why Automated Tracking?
Exchange rates are affected by a wide range of economic and political
factors, resulting in constant fluctuations. For investors, businesses,
and analysts:
Constant Fluctuations: make manual tracking
impractical and prone to error.
The Need for Accuracy: financial decisions
require accurate, real-time data.
Lost Opportunities: delays in obtaining data can
lead to missed investment opportunities or increased risk.
Our project aims to overcome these challenges by automating the data
collection and analysis process..
#2. Our Innovative Solution: Real-Time EUR/USD Tracking
We offer a comprehensive solution that combines Google Sheets, Google
Apps Script, and Tableau (or Looker Studio) technologies to create an
automated monitoring and analysis system for the EUR/USD currency
pair.
Key Components of the Solution:
- Automated Data Collection:
- Historical Data Storage:
Tool: Google Sheets (USDEUR Summary
Sheet)
Function: Records historical data on price,
changes, and trend status.
- Powerful Business Intelligence:

#3. In-Depth Look: The Data Engine - Google Sheets & Apps
Script
Google Sheets forms the backbone for data collection, storage, and
initial analysis. Its capabilities are enhanced by Google Apps Script to
automate key tasks.
##3.1. LIVE_DATA Sheet: Fetching Real-Time Price
This sheet is used to continuously fetch the latest EUR/USD exchange
rate.
- Function: Fetches the current price, date and time,
and the previous price for the currency pair.
- Source: Releases on the powerful
GOOGLEFINANCE function to fetch real-time financial
data.

EUR/USD exchange rate is fetched.
##3.2. USDEUR Summary Sheet: Historical Data Record
This sheet is the main repository for all collected historical data
points.
- Function: Stores each exchange rate record with the
date and time, previous rate, daily (or 30-minute) change, and trend
status (UP/DOWN/FLAT).
Trend Status Column: This column is
calculated by comparing the current price to the previous price,
providing an immediate view of the trend at each point in time.

data history of the EUR/USD rate in the USDEUR Summary
sheet.
##3.3. Statistical Summary Sheet: Raw Key Performance
Indicators
This sheet provides a concise statistical summary of exchange rate
data. This is the direct source of the Key Performance Indicators (KPIs)
in the dashboard.
- Function: Automatically calculates the latest
exchange rate, all-time average price, price volatility (standard
deviation), current trend status, and total number of records.
- Benefits: Provides a quick overview of the most
important metrics without the need to analyze raw data.

summary and raw key performance indicators (KPIs) in the

3.4. Data Automation Using Google Apps Script
This is where the power of automation lies. A custom Google Apps
Script fetches and records data regularly, ensuring that our historical
log and statistical summaries are always up-to-date.
Reads the latest EUR/USD rate from the LIVE_DATA
sheet.
Calculates the previous rate by looking at the last recorded
entry in the USDEUR Summary.
Adds a new row to the USDEUR Summary sheet
containing the current timestamp, current rate, previous rate, and other
derived metrics.
Ensures that calculated columns (such as daily change and trend
status) in USDEUR Summary are correctly populated for the
new row.
Executes this operation every 30 minutes using a time-driven
trigger configured in Google Apps Script.
- Script Code
(
recordHistoricalRate()):
````javascript
function recordHistoricalRate() {
const HISTORY_SHEET_NAME = 'USDEUR_Summary';
const LIVE_SHEET_NAME = 'LIVE_DATA';
try {
const ss = SpreadsheetApp. getActiveSpreadsheet();
const historySheet = ss. getSheetByName(HISTORY_SHEET_NAME);
const liveSheet = ss. getSheetByName(LIVE_SHEET_NAME);
// Get the last row with content in the history sheet to determine where to append the new row
const lastRowInHistory = historySheet. getLastRow();
const newRowIndex = lastRowInHistory + 1;
// Read the current price from the live data sheet.
//Assuming EUR_RATE is in cell A1 of LIVE_DATA sheet based on your code snippet
const EUR_RATE = liveSheet.getRange('A1').getValue();
// Get the previous rate from column E (5th column) of the last recorded row in HISTORY_SHEET_NAME.
// We assume column E in USDEUR_Summary holds the "Current Rate" of the previous entry.
let previousRate = 0;
if (lastRowInHistory > 1) { // Ensure there's a previous record to read from (assuming header in row 1)
previousRate = historySheet. getRange(lastRowInHistory, 5). getValue();
} else {
// If this is the first data entry after headers, previousRate can be set to currentRate or 0
previousRate = EUR_RATE;
}
// Create the new data row to be appended to USDEUR_Summary
// The structure should match the columns in USDEUR_Summary:
// A: Metric, B: Last Updated (CET), C: Source Currency, D: Target Currency, E: Exchange Rate, F: Previous Day's Rate, G: 30 minutes Change (%), H: Trend Status
// Note: Columns G and H will be populated by formulas if they exist in G2:H2
const rowData = [
"USD to EUR Rate", // Column A: Metric
new Date(), //Column B: Last Updated (CET) - Current timestamp
"USD", // Column C: Source Currency
"EUR", // Column D: Target Currency
EUR_RATE, // Column E: Exchange Rate (Current Rate)
previousRate // Column F: Previous Day's Rate
];
// Add the row to the history sheet
historySheet. appendRow(rowData);
// Copy formulas for '30 minutes Change (%)' and 'Trend Status' to the new row
// Assuming formulas for these are in columns G and H of row 2
historySheet.getRange("G2:H2"). copyTo(historySheet.getRange(newRowIndex, 7, 1, 2));
Logger.log("Historical record added successfully to " + HISTORY_SHEET_NAME + " at row " + newRowIndex);
} catch (e) {
Logger.log("Error recording data: " + e.toString());
// Optionally, send an email notification about the error
// MailApp.sendEmail("your_email@example.com", "Apps Script Error - EUR/USD Tracker", "Error: " + e.toString());
}
}
Detailed Script Explanation:
This script performs the following steps periodically:
Select Sheets: Selects the
USDEUR_Summary and LIVE_DATA sheets in the
active data table.
Fetch Current Price: Reads the latest
EUR/USD price from cell A1 in the LIVE_DATA
sheet.
_Fetch Previous Price: Extracts the price
recorded in column 5 (E) from the last row added in the
USDEUR_Summary sheet. If there are no previous records, the
previous price is considered the same as the current price to prevent
errors.
Set up data for the new row: Creates a new data
row containing a description of the scale, the current date and time,
the source and target currencies, the current price, and the previous
price.
Add row: Adds the new row to the
USDEUR_Summary sheet.
Copy formulas: Copys the formulas in cells
G2:H2 (for “30 minutes Change (%)” and “Trend Status”) to
the new row, ensuring these values are automatically calculated for each
new entry.
Error logging: Includes error handling that logs
any problems that occur during execution in the
Logger.
- Set up the time-driven trigger:
To run this script automatically every 30 minutes, a time trigger
must be set up in Google Apps Script:
In the Google Apps Script editor, click the icon 1. Click on the
Triggers (clock icon) in the left sidebar.
Click on + Add Trigger in the bottom right
corner.
Select the function you want to run:
recordHistoricalRate.
Set the Event type to
Time-driven.
Select the Time-based trigger type to
Every 30 minutes.
Save the trigger.
Result: The data collection and logging process is
now fully automated, ensuring your dashboard is regularly updated.
